CORNrPOPPING MACHINE.

To 0. whom it may concern: Be it known that 1, WILLIAM RYAN, a citi zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corn-Popping Machines, of which the following is a specification.

This invention relates to improvements in corn-popping machines.

The objects of this invention are, first, to rovide an im roved corn-popping machine by which the iability of burning the corn is reducedto a minimum; second,to provide an improved corn-popping machine which is of very large capacity in proportion to size and easy to operate; third, .to provide an improved corn-popping machine embodying these advantages which is simple in structure and economical to manufacture.

Furtherobjects and objects relatin to structural details will definitely appear om the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

- A structure embodying the features of my. invention is clearly illustrated in the accompanying drawings, forming a part of this specific'ation, in which Figure 1 is a front elevation View of my improved corn-popping machine, portions being broken away to show structural details. Fig. 2 is a detailsi'de elevation view of my improved corn popping machine looking from the right of Fig. 1. Fig. 3 is a detail side elevation View showing the popper-box adjusted to its discharging position. Fig. 4

ogis' an enlarged detail view of the popper- -'line 5 5 of Fig; 2.

box,'taken on a line corresponding to line 4 4 of Fig. 2. Fig. 5' is a detail vertical sectional view taken on a line corresponding to In the drawings similar letters of reference refer to similar parts throughout the several views, and the sectional-views are taken looking in the direction of the little arrows at the ends of the section-lines.

Referring to the drawings, the main or supporting frame is preferably made up of standards A, having cross-pieces A A rigidly secured thereto. A 'popper-boxcarry-1 ing frame C is provided. The popper-box G is hinged at its forward end to the frame C.

Specification of Letters Patent.

Application filed August '7, 1905. Serial No. 273,210.

The frame C is supported by the arms B. The arms B are pivotally mounted on the rods B at their lower ends, and their upper ends are pivotally connected to the frame C by the rods 0. The pivot-rods B are supported by the brackets a. A pair of angleiron rests C are secured to the popper-boxcarrying frame 0 in position to receive and hold the popper-box.

The popper-box G is preferably made with sheet-metal sides and with a screen-bottom. A portion of the topof the popper-box is also covered with screen. The popper-box door G! is hinged at g and is adapted to open upwardly. The side rails G of the popper-box are extended forward beyond the box to gage the upward-projecting catches h, se-

cured to the side walls of the popper-box.

(See Figs. 1 and 3.) The bolts h are arranged through suitable guides on the popper-box door and are connected by links H to the latch-lever H, which is pivoted at g. By lifting this latch-lever the bolts are first withdrawn, and then the door is opened. Stops h are arranged on the bolts to limit their inward movement. The latch-lever H is connected by a cable i, which is arranged over the guide-pulley I on the rear of the popperbox, to the frame C. When the popper-box G is tilted to dump the same, the latch-arm H is lifted, first Withdrawing the latch-bolts from their catches and then' lifting the door to allow the discharge of the popped corn. A handle J is The position 0 the box when tilted is illustrated in Fig. 3.

A vibratory movement is imparted to the popper-box by means of the springs E, which are secured on the cross-piece a, at their lower ends and connected to the cross-rod c of the popper-box-carrying frame at their upper ends. These springs are connectedby means of the rods E to the crank-shaft F. The cross-pieces a are preferably mounted on brackets a, projecting from the sides of the main frame. r I 1;

A pair of vibrating springs D are arranged rovided for tilting the box.

on each side of the machine to assist in vibrating the popper-box. These springs are secured to the cross-pieces a at their lower ends; but their upper ends are hooked over the cross-rods c of the popper-box frame C. This when in operation keeps the popperbox vibrating in a manner that thoroughly agitates the corn, keeping it in motion, so that liability of its catching fire is reduced to a mlnimum.

While I prefer to operate the machine by power, it is evident that it can be operated by hand, either by a suitable crank on the crankshaft or by means of the handle J.

Any suitable burner, as L, may be arranged beneath the popper-box, or a charcoal box or other heating means can be located under the same, as may be desired.

The operation of the machine keeps the corn in the popper-box thoroughly agitated. When done, it is only necessary to tilt the popper-box on its hinges b, which open the door, and the popped corn passes out over the screen Ur, thereby screening it. The screened corn may be delivered into one receptacle and the screenings into another, the latter being collected from the screen G by the chute K. When the popper-box is allowed to drop into its normal position, the door is automatically closed and locked.

The structure is comparatively simple and economical to manufacture and is very convenient to use. It may be of comparatively small size and still of very large capacity on account of its convenience in use and the thorough agitation of the corn in the popperbox.

I have illustrated and described my improved popper-box in detail in the form preferred by me on account of its structural simplicity, economy, and convenience in use, al though I am aware that it is capable of considerable variation in structural details with out departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
